Overview
The LC74780 and LC74780M are CMOS, video display
controllers for superimposing text and low-level graphics
onto an NTSC, PAL or PAL-M compatible television re-
ceiver. Up to 288, 12
× 18-pixel characters can be displayed
under microprocessor control on a 24-character by 12-line
display.
The LC74780 and LC74780M feature selectable pixel width
and height, and 64 vertical and 64 horizontal display start
positions. It also features a flashing enable bit for each char-
acter position.
The LC74780 and LC74780M operate from a 5V supply.
The LC74780 is available in 24-pin DIPs, and the
LC74780M, in 24-pin MFPs.
